Adeptus Custodes Gain Expanded Martial Ka'tahs and Defensive Rules in New Codex
The new Codex: Adeptus Custodes introduces six flexible martial ka'tahs, replacing the previous two, allowing units to act in any phase. It also restores Aegis of the Emperor as a Feel No Pain 5+ ability and adds Aquila Commander for extra Command Points. Sisters of Silence gain a psychic null aura to protect nearby Custodians.
